20399518 ÷ 331 
We're looking to find how many times 331 goes into 20399518.

Moving on to step 1:
331 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 331

Let's proceed to step 2:
The number 331 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 331

On to step 3:
The number 331 fits into 203 0 times, leaving a remainder of 203.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 203, we get 203.
Append the next digit (9) from the dividend to 203 and continue with: 2039 / 331

Moving on to step 4:
When dividing 2039 by 331, we get 6 with a remainder of 53.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 1986 from 2039, we get 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 331

Step 5:
The number 331 fits into 539 1 times, leaving a remainder of 208.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
The remainder is 208 after subtracting 331 from 539.
Fetch the next digit (5) from the dividend, attach it to 208 and continue: 2085 / 331

Moving on to step 6:
The number 331 fits into 2085 6 times, leaving a remainder of 99.
The number 6 becomes the next digit in our result. 
Result so far: 616.0
Deduct 1986 from 2085 and we're left with 99.
Include the next digit (1) from the dividend after 99, then repeat: 991 / 331

Advancing to step 7:
331 goes into 991 2 times with a remainder of 329.
The next digit of our result is 2. 
Result so far: 6162.0
If we take 662 away from 991, we end up with 329.
Fetch the next digit (8) from the dividend, attach it to 329 and continue: 3298 / 331

Moving on to step 8:
3298 divided by 331 is 9 with a remainder of 319.
The next digit of our result is 9. 
Result so far: 61629.0
Subtract 2979 from 3298 to get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

On to step 9:
331 goes into 3190 9 times with a remainder of 211.
Put 9 as the next digit of the answer. 
Result so far: 61629.9
If we subtract 2979 from 3190, we get 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Let's proceed to step 10:
If we divide 2110 by 331, we get 6 and a remainder of 124.
Write down 6 as next digit of the result. 
Result so far: 61629.96
If we subtract 1986 from 2110, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 11:
The number 331 fits into 1240 3 times, leaving a remainder of 247.
The next digit of our result is 3. 
Result so far: 61629.963
Subtract 993 from 1240 to get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 12:
When dividing 2470 by 331, we get 7 with a remainder of 153.
Record the quotient 7 as the next digit in the result. 
Result so far: 61629.9637
Subtract 2317 from 2470 to get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 13:
1530 divided by 331 is 4 with a remainder of 206.
Put 4 as the next digit of the answer. 
Result so far: 61629.96374
Deduct 1324 from 1530 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Step 14:
2060 divided by 331 is 6 with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 61629.963746
The remainder is 74 after subtracting 1986 from 2060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 15:
331 goes into 740 2 times with a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 61629.9637462
If we take 662 away from 740, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 16:
The number 331 fits into 780 2 times, leaving a remainder of 118.
The number 2 becomes the next digit in our result. 
Result so far: 61629.96374622
Deduct 662 from 780 and we're left with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

The quotient of the division is 61629.96374622, and the remainder is 1.18e-07.
